  • Performance and emission characteristics with kerosene blending with diesel on a single cylinder four stroke Cycle direct injection diesel engine
    International Journal of Managment IT and Engineering, 2020
    Co-Authors: M. Marouf Wani, M. Shafi Charoo
    Abstract:

    This paper describes the experimental investigations with kerosene blending with diesel on a single cylinder four stroke Cycle direct injection diesel engine. Kerosene is inferior petroleum distillation fraction and is conventionally used in stoves used for cooking. The engine was mounted on test bed and fitted with attachments like hydraulic dynamometer, fuel consumption and air consumption measuring systems. Exhaust gas analyzer was used for measuring emissions. The engine was run in the neat diesel mode and data was collected for power, speed, air and fuel consumption. Exhaust emissions were also measured. The experiments were repeated for 30% and 50% kerosene-diesel blends. Thermodynamic analysis was done in both cases. It was seen that the power output was improved with kerosene adulteration in diesel. There was also reduction in the brake specific fuel consumption and opacity (exhaust emissions) with increased kerosene substitution in diesel.

  • Computational performance evaluation of a four stroke Cycle spark ignition engine using petrol and propane as alternative fuels
    International Journal of Management IT and Engineering, 2020
    Co-Authors: M. Marouf Wani, Shahid Saleem
    Abstract:

    This paper describes the results of computational studies on a single cylinder four stroke Cycle spark ignition engine using Propane as an alternative fuel to petrol. The simulation is done in the professional engine simulation software from AVL Austria named as BOOST. The modeling methodology involves the use of first law of thermodynamics for engine as an open system when valves are open and engine as a closed system when valves are closed. To include the effect of gas exchange in the intake and exhaust manifolds when the valves are open, the modeling is done using Navier -Stokes equations for manifolds. The design parameters are fixed by engine geometry. A matrix was prepared for the operating variables to carry out the simulation. First the data was used as per petrol engine needs, and results for engine performance were generated. The operation was revised with data for proposed propane fuelled engine and its performance were studied. The software gave successful results in both the cases. It was observed that the power output was increased with propane as an alternative fuel due to its higher calorific value, there was reduction in brake specific fuel consumption due to higher calorific value of propane. The emissions will also reduced with propane as fuel because of less carbon atoms in propane as compared to petrol fuel. It is proposed that propane can be successfully used in petrol engine as an alternative fuel.

  • Computer simulation studies on a four stroke Cycle spark ignition engine using gasoline and hydrogen as alternative fuels
    International Journal of Managment IT and Engineering, 2020

    Abstract:

    This paper describes the results of computational studies on a single cylinder four stroke Cycle spark ignition engine using Hydrogen as an alternative fuel to petrol. The simulation is done in the professional engine simulation software from AVL Austria named as BOOST. The modeling methodology involves the use of first law of thermodynamics for engine as an open system when valves are open and engine as a closed system when valves are closed. To include the effect of gas exchange in the intake and exhaust manifolds when the valves are open, the modeling is done using Navier -Stokes equations for manifolds. The design parameters are fixed by engine geometry. A matrix was prepared for the operating variables to carry out the simulation. First the data was used as per petrol engine needs, and results for engine performance and emissions characteristics were generated. The operation was revised with data for proposed hydrogen engine and its performance and emissions characteristics were studied. The software gave successful results in both the cases. It was observed that the power output was decreased with hydrogen as an alternative fuel due to lower volumetric efficiency, the brake specific fuel consumption was comparable in both cases due to higher calorific value of hydrogen. The emissions were also reduced with hydrogen as fuel because of no carbon atoms as compared to petrol fuel. No CO emission was produced with hydrogen, there was reduction in NOx emission and also there was drastic reduction in hydrocarbon emissions with hydrogen as fuel. It is proposed that hydrogen can be successfully used in petrol engine as an alternative future fuel.

  • Comput er Simulation Studies on a Single Cylinder Four Stroke Cycle Spark Ignition Engine Using Gasoline and Blend of Ethanol and Gasoline as Alternative Fuels
    2020
    Co-Authors: M. Marouf Wani, M Mursaleen
    Abstract:

    This paper describes the results of computational studies on a singlecylinder four stroke Cycle spark ignition engine using ethanol-gasoline blends as an alternative fuel to petrol. The simulation is done in the professional engine simulation software from AVL Austria named as BOOST( AVL, 2009). The modeling methodology involves the use of first law of thermodynamics and Navier -Stokes equations. The software gave successful results in both the cases. It was observed that the power output was reduced by about 35% with 85% ethanol blended gasoline as an alternative fuel due to its lower calorific value, there was increase in brake specific fuel consumption due to lesser  power under similar conditions and due to lower calorific value of ethanol blended gasoline. The CO emissions were reduced with ethanol blends as fuel because of less carbon atoms, NOx was reduced with ethanol blended gasoline due to lesser exhaust gas temperatures as compared to pure gasoline. The exhaust gas temperatures were higher by about 12% with pure gasoline mode , and HC emissions were also reduced  with ethanol blends due to better combustion as the inherent oxygen in ethanol assists in combustion.  it is proposed that 85% ethanol +15% gasoline blend can be successfully usedin petrol engine as an alternative fuel.

  • Investigation of combustion characteristics and emissions in a spark-ignition engine fuelled with natural gas–hydrogen blends
    International Journal of Hydrogen Energy, 2020
    Co-Authors: Nafiz Kahraman, Bilge Albayrak Ceper, S. Orhan Akansu, Kadir Aydin
    Abstract:

    Abstract In this study, an experimental study on the performance and exhaust emissions of a spark-ignition engine fuelled with methane–hydrogen mixtures (100% CH4, 10% H2 + 90% CH4, 20% H2 + 80% CH4, and 30% H2 + 70% CH4) were performed at different engine speeds and different excessive air ratios. This present work was carried out on a Ford engine. This is a Four-Stroke Cycle four-cylinder spark-ignition engine with a bore of 80.6 mm, a stroke of 88 mm and a compression ratio of 10:1. Experiments were performed at 1500, 2000, 2500 and 3000 rpm and at wide open throttle (WOT). CO, CO2 and HC emission values and cylinder pressure were measured. The results showed that while the speed and excessive air ratio increase, CO emission values decrease. The reduction of HC and CO emissions could be obtained by adding hydrogen into the natural gas when operating on the lean mixture condition. Increasing the excessive air ratio also decreases the maximum peak cylinder pressure.

  • Experimental investigation of the effect of spark plug gap on a hydrogen fueled SI engine
    International Journal of Hydrogen Energy, 2012
    Co-Authors: Bilge Albayrak Ceper
    Abstract:

    In this work, an experimental study on the performance and exhaust emissions of a commercial hydrogen fueled spark ignition engine (HFSIE) was performed at partially and full wide open throttle (50% and 100% WOT) positions. The engine is a Four-Stroke Cycle six-cylinder, engine volume of 4.9 L, port fuel injection, hydrogen fueled SI engine with a bore of 102.1 mm, a stroke of 101.1 mm and a compression ratio of 13.5:1. The experiments were performed using 3 different spark plug gaps (SPG) (0.4, 0.6 and 0.8 mm), varied engine speeds of 1000-3000 rpm and two ignition timing values (10 and 15°CA BTDC) at 50% and 100% wide open throttle (WOT). SPG is a factor affecting the performance of the engine depending on the engine structure. Maximum power values were obtained at 0.6 mm SPG for both 50% and 100% WOT at ignition timing values of 10 and 15°CA BTDC. The maximum efficiency values were obtained with a 0.8 mm SPG at 50% WOT. At 100% WOT position, the maximum efficiency values were obtained with a 0.6 mm spark plug gap (SPG) at ignition timing values of 10 and 15°CA BTDC. A significant decrease in NO emission was observed using hydrogen for all WOT and SPGs. Copyright © 2012, Hydrogen Energy Publications, LLC. Published by Elsevier Ltd. All rights.
